Mr. Yamada, whose full name is Kento Yamada, is the father of the Yamada family in the anime Chi's New Address. He works as a graphic designer and is the husband of Miwa and the father of their son Youhei, who found the kitten Chi. Mr. Yamada cares deeply for Chi, treating her as a beloved member of the family. He often buys toys and snacks for her and worries about her being lonely when left alone at home. His role in the story is that of a supportive parent who helps navigate the challenges of living with a cat in an apartment complex that now allows pets. He is the one who takes Chi to the veterinarian, an experience that briefly causes Chi to be angry with him, but this does not diminish his affectionate nature. Throughout Chi's New Address, Mr. Yamada remains a steady, gentle presence who prioritizes Chi's well-being and happiness, adapting to the family's move to a pet-friendly home without significant personal development but consistently demonstrating his commitment to his family. His notable abilities are not emphasized beyond his profession and his patient, caring approach to pet ownership.
